through the post and lintel system, the loads are transmitted from top to support, up the foundations.
this system of posts and lintels, only seen in the structure, but is also present within the wall in the openings of windows and doors.
the lintel supports the loads and leads through post to foundations
the lintel length also depends on the material used to its construction and its resistance to flexion
the post provides support to the lintel and the loads falling on him should therefore be constructed a material that is resistant to compression.
the brick masonry is efficient as post but not as lintel because the mortar that binds them to each other, is more resistant in compression than in flexion.
with the use of materials more resistant to flexion, lintels can be constructed for opening more space between the posts
